A button sensor generally requires one sequencer stage; this is
shown in Figure 26 as B1. However, it is possible to configure
two button sensors to operate differentially for one conversion
stage. Only one button can be activated at a time; pressing both
buttons simultaneously results in neither button being activated.
The configuration with two button sensors operating differentially
requires one conversion stage and is shown in Figure 26, with
B2 and B3 representing the differentially configured button sensors.
A wheel sensor requires eight stages, whereas a slider requires two
stages. The result from each stage is used by the host software to
determine the user’s position on the slider or wheel. The algorithms
that perform this process are available from Analog Devices and are
free of charge, but require signing a software license.
